2015 Wimbledon Championships – Men's singles

Defending champion Novak Djokovic defeated Roger Federer in a rematch of the previous year's final, 7–6(7–1), 6–7(10–12), 6–4, 6–3 to win the gentlemen's singles tennis title at the 2015 Wimbledon Championships. It was his third Wimbledon title and ninth major title overall. Federer was vying to become the first man to win Wimbledon eight times (a feat he would achieve in 2017), and became the first man in the Open Era to reach 10 finals at the same major.

In the second round, 102nd-ranked Dustin Brown upset the two-time champion Rafael Nadal. Brown previously defeated Nadal on a grass court just a year prior at the Gerry Weber Open, the only other time the two had played each other. This marked the fourth straight year in which Nadal suffered an early exit from the tournament by losing to a player ranked 100 or lower.

2002 champion Lleyton Hewitt made his final Wimbledon singles appearance, losing to Jarkko Nieminen (who was also playing in his final Wimbledon) in the first round. This was the first major since the 2002 US Open where then-world No. 8 David Ferrer did not participate (due to an elbow injury), ending his streak of 50 consecutive major appearances. This was also the first major main draw appearance for future two-time ATP Finals champion and Olympic gold medalist Alexander Zverev; he lost to Denis Kudla in the second round.
